TPE and RAC Audit Support for Skilled Nursing Facility (SNF): Skilled Therapy Minutes Documentation

Therapy documentation remains a significant audit focus for Skilled Nursing Facilities even though the Patient Driven Payment Model removed therapy minutes as the primary driver of payment classification. While PDPM shifted the payment calculation toward diagnosis and clinical condition-based classification, therapy documentation still matters enormously for two distinct reasons: it establishes that skilled therapy services were medically necessary and genuinely furnished as billed, and it supports compliance with PDPM’s specific limits on group and concurrent therapy delivery. Both Targeted Probe and Educate (TPE) reviews conducted by Medicare Administrative Contractors and Recovery Audit Contractor (RAC) complex reviews continue to examine therapy documentation closely, even in the current payment environment.

This article explains how skilled therapy documentation requirements have evolved under PDPM, the specific group and concurrent therapy limit and how it is measured, the medical necessity documentation standard that continues to apply regardless of payment methodology, and how SNFs should structure an effective TPE or RAC response when therapy documentation is challenged. It closes with how HealthBridge US supports SNFs strengthening skilled therapy minutes documentation.

Why Therapy Documentation Still Matters Under PDPM

Under the prior RUG-IV payment system, therapy minutes directly determined payment classification, creating a documentation focus almost entirely centered on verifying that billed minutes matched actual therapy delivery. PDPM removed this direct link between minutes and payment, classifying residents based on clinical characteristics rather than therapy volume. However, this change did not eliminate the underlying requirement that skilled therapy services be medically necessary, reasonable, and actually furnished as documented — it simply changed which specific compliance question dominates therapy-related audit activity.

Under PDPM, therapy documentation audits focus on two primary questions: first, whether the therapy services furnished were genuinely skilled and medically necessary, requiring the specific expertise of a licensed therapist rather than services that could be provided by non-skilled staff; and second, whether the facility’s therapy delivery complied with PDPM’s specific limit on group and concurrent therapy modes, since this limit is a distinct compliance requirement independent of the broader medical necessity question.

The Group and Concurrent Therapy Limit

PDPM limits the combined use of group and concurrent therapy modes to no more than 25 percent of the total therapy minutes furnished per discipline — physical therapy, occupational therapy, and speech-language pathology — measured across the entirety of the resident’s Part A stay, from the first day through the last. This means therapy must be delivered on an individual basis for at least 75 percent of the total treatment time within each discipline across the full stay, not simply on any given day or treatment session.

Compliance with this limit is measured and reported through specific items on the PPS Discharge Assessment, which capture the total minutes furnished by mode — individual, concurrent, and group — for each discipline across the entire Part A stay. If the calculated ratio of combined concurrent and group minutes to total minutes exceeds 25 percent for any discipline, the assessment generates a non-fatal warning edit, which flags the finding without independently denying the claim. This means the 25 percent limit is a compliance benchmark drawing attention to a facility’s therapy delivery pattern, rather than a hard payment cap that automatically triggers denial on its own — however, exceeding this benchmark can still contribute to a broader review if the pattern raises other medical necessity or documentation concerns.

Documentation Elements Supporting Skilled Therapy Medical Necessity

Regardless of the delivery mode used, therapy documentation must establish that the specific services furnished required the skills of a qualified therapist — meaning the complexity of the resident’s condition, the therapeutic techniques employed, and the clinical judgment involved in delivering and adjusting the intervention could not have been performed safely and effectively by non-skilled personnel. Documentation that describes only routine exercises or general activity without connecting those interventions to a specific therapeutic goal and the clinical reasoning behind the chosen approach is vulnerable to a medical necessity challenge, since it may not clearly establish that skilled intervention, as opposed to general activity, was genuinely required.

Documentation should also reflect the resident’s response to treatment and progress toward established functional goals over time, since a lack of documented progress, without a clear clinical explanation, can raise questions about whether continued skilled therapy remained medically necessary throughout the stay. Where group or concurrent therapy is used, documentation should specifically identify the mode of delivery for each session and, where clinically relevant, the rationale for that mode choice, supporting the facility’s own tracking of its cumulative mode ratio across the stay.

Building an Effective TPE or RAC Response

When a MAC issues a TPE probe notice or a RAC issues a request for documentation supporting SNF therapy billing, the response should assemble the complete therapy record for the relevant stay: initial evaluations, treatment notes for each session reflecting the specific interventions furnished and the mode of delivery, progress notes documenting the resident’s response and functional progress, and, where relevant, the facility’s own calculation of the discipline-specific concurrent and group therapy ratio for the stay. The response narrative should directly address the medical necessity of the skilled interventions furnished, connecting specific documented interventions to the resident’s clinical condition and functional goals, rather than relying on a general assertion that skilled therapy was appropriate throughout the stay.

For TPE reviews specifically, SNFs should use the individualized education provided after each review round to correct systemic documentation patterns — for example, treatment notes that consistently describe interventions in generic terms without connecting them to specific therapeutic goals — before the review escalates further. Response timelines for RAC-issued requests generally follow the standard 30- to 45-day Medicare ADR framework.

Common Documentation Gaps in Skilled Therapy Review

Several recurring gaps appear in SNF therapy documentation review. Treatment notes that record session duration and general activity type without connecting the intervention to a specific therapeutic goal or documenting the clinical reasoning behind the chosen approach are among the most frequently cited deficiencies, since they make it difficult for a reviewer to confirm that skilled, rather than routine, services were furnished. Notes that do not clearly identify the mode of delivery for each session create difficulty verifying compliance with the 25 percent concurrent and group therapy limit, particularly when a facility’s own internal tracking depends on accurate mode documentation at the point of care rather than reconstruction at the time of discharge assessment completion. Progress documentation that repeats similar language across multiple sessions, without reflecting the resident’s actual evolving functional status, can also undermine the broader medical necessity narrative even when raw therapy minutes are accurately documented.

Staffing Model Considerations and Documentation Consistency

The specific staffing model a SNF uses for therapy delivery — employed therapists, contracted therapy companies, or a hybrid arrangement — can influence documentation consistency in ways facilities should actively manage. Contracted therapy staff may bring documentation habits and templates from other facilities or from their contracting company’s standard practices, which may not fully align with a specific SNF’s internal documentation expectations or its approach to tracking the concurrent and group therapy ratio. SNFs using contracted therapy services should ensure their contracts and onboarding processes explicitly address the facility’s documentation standards, including the specific content expected in treatment notes and the facility’s method for tracking mode-of-delivery data throughout a resident’s stay, rather than assuming a contracted provider’s general documentation practices will automatically align with the facility’s own compliance needs. Regular communication between facility MDS and compliance staff and contracted therapy leadership, including periodic joint review of a sample of recent documentation, helps ensure consistency regardless of which specific staffing model the facility uses.

Building Proactive Therapy Documentation Practices

SNFs that experience fewer therapy-related denials generally implement structured treatment note templates that prompt therapists to document the specific therapeutic goal, clinical reasoning, and mode of delivery for every session, rather than relying on free-text narrative alone. Real-time tracking of the cumulative concurrent and group therapy ratio throughout a resident’s stay, rather than only calculating it at discharge, allows therapy staff to adjust delivery mode proactively if a discipline is trending toward or beyond the 25 percent benchmark well before the stay concludes. Regular internal audits sampling therapy documentation against both the skilled medical necessity standard and mode-of-delivery tracking accuracy help SNFs identify and correct gaps before an external MAC or RAC review does.

Coordinating a Response When TPE and RAC Reviews Overlap

Because a MAC’s TPE program and a nationwide RAC review can both examine SNF therapy documentation at the same facility, sometimes concurrently, compliance staff benefit from tracking both types of inquiry together rather than treating them as unrelated correspondence. A documentation gap identified during a TPE round — for example, a pattern of treatment notes lacking a clear connection between the intervention and a specific therapeutic goal for a particular therapist — is often the same underlying issue a RAC would identify independently if it selected a broader sample of the same facility’s claims. Addressing the pattern once, through targeted therapist education and a revised documentation template, is more efficient than responding to each contractor’s request as an isolated event that leaves the same systemic issue unaddressed for whichever reviewer examines the facility’s claims next.

Why the Non-Fatal Warning Edit Still Warrants Attention

SNFs should not interpret the absence of an automatic payment denial tied to the 25 percent concurrent and group therapy limit as a signal that this compliance area can be deprioritized. While CMS’s current enforcement approach generates a non-fatal warning rather than an automatic denial when the ratio is exceeded, a facility with a sustained pattern of ratio violations across many residents and reporting periods creates exactly the kind of statistically visible pattern that can draw broader program integrity attention, independent of whether any single claim was denied on this basis alone. Facilities should treat the 25 percent benchmark as a genuine compliance standard warranting proactive management, not merely a data point that carries no practical consequence, since CMS’s enforcement posture in this area could also evolve over time as the agency gains more experience with PDPM’s practical operation.
